I've recently built a computer for a friend, its not the first computer I've built but I'm not entirely confident about it.
The problem is every now and then, seems to be while more CPU intensive tasks are being carried out, the computer just switches off and restarts. At the moment my friend is recording a lot of music onto their system and although the computer is on most of the day it only seems to switch off while its recording. When it does switch off it seems to do it several times in a row, and then it is left for while and its fine.
The motherboard is an ASUS A7N8X and i thought initially that the processor could be overheating (i had a little trouble with the heatsink, when i built it)and the motherboard was switching off automatically, but it seems to be running below threshold (between 30-50°C) so i dont think its that.
Could it be the power supply? unfortunately we didn't have a huge budget and i didn't know the risk at the time but we bought a £22 mercury case + psu from addonsonline.
Any help would be appreciated, thanks
